I will start just by saying that I’m not a person that has practiced the glitch art form, but having been exposed to some examples of it, it’s not hard to recognize it. The difference is that this particular glitch … Continue reading

Hack: Customize the LED Shake-Stick Images

As I managed to construct the LED shake-stick kit just yesterday evening, I wasn’t entirely satisfied with its operation. For one, the images weren’t particularly inspiring. I mentioned that it should be possible to replace the images in the ROM … Continue reading

Project: AT89S52+DS1302-based LED Clock Kit (EC1204B-Equivalent)

Telstra FaxStream TestFax Professional (aka FOLDS-B) Test
